According to OU spokeswoman Catherine Bishop, shortly before 2 p.m., a black book bag was found unattended at the Sam Noble Oklahoma Museum of Natural History.

The museum was evacuated, she said, and university police conducted a search of the premises with the help of bomb-sniffing dogs.

Bishop said the Norman Police Department bomb squad was also notified. Crews at the scene took an x-ray of the bag and determined that it was a normal backpack.

The all-clear has been given.
